A new general rainfall intensitydurationfrequency formula is presented, utilizing a method similar to, but more accurate than one previously developed. The previously developed formula was based on the average depthduration ratio of about 40 percent and the mean depthfrequency ra...

Intensity – Duration – Frequency (IDFTen year-hourly rainfallIranRainfall intensity with different frequencies is needed for many hydrologic models. Rainfall intensity鈥揹uration鈥揻requency relationships (IDF) have been investigated for different regions using previously recorded data. Iran Meteorological ...
Rainfall intensityisdefinedas the ratio of the total amount of rain (rainfalldepth) falling during a given period to the duration of the period It is expressed in depth units per unit time, usually as mm per hour (mm/h). The statistical characteristics of high-intensity, short-duration, con...
9.3.2.2 Rainfall intensity The rainfall intensity I is determined from intensity-duration-frequency (IDF) charts developed by the National Weather Service. Fig. 9.2 shows a typical IDF chart for Raleigh, North Carolina. Sign in to download full-size image Figure 9.2. Intensity-duration-frequency ...
The intensity-duration-frequency curves are used in hydrology to express in a synthetic way, the link between the maximum rainfall height h and a generic duration d of a rainfall event, fixed a given return period T. Generally, IDF curves can be characterized by a bi-parameter power law: ...
Rainfall frequency distributionRainfall intensityRainfall durationArid basinsSaudi ArabiaIn this study, rainfall analysis is carried out to investigate the areal rainfall characteristics of three major basins in western Saudi Arabia. The drainage area of study basins ranges from 395 to 3500km 2 . ...
Current infrastructure design of water systems, however, is based on intensity-duration-frequency (IDF) curves that assume extreme precipitation will not significantly change. To sustain the reliability of infrastructure designs in a changing environment, time-varying nonstationary-based IDF curves ...
